relation with respect to each other, whereby an inclined ventilating opening of variable size is provided between the cross rails and communicating with both the inside and the outside atmos- 5 phere.

The upper sash comprises a cross rail 19, side rails 20, a pane 2| held in by putty or the like 22, and an upper cross rail 23 having a cross section approximating a right angled triangle,

similar to the cross rail 14 and having its longer side projected from the sash in a vertical plane, the hypothenuse of the triangle constituting an inclined or beveled surface 25. A fixed cross rail portion 2! also is provided, similar in cross sec- 15 tion to the fixed rail I5 having the short side of the triangle abutting the lintel 4 and with its longer side projecting downwardly in a vertical plane, the hypothenuse 26 intersecting the vertical side to provide a free edge 32. The beveled surfaces or hypothenuses and 28 and the projected edges 3| and 32 are in precisely the same relation as the beveled surfaces I6 and I1 and free edges 29 and 3t, and cooperate in the same manner. Duplicate description of the functions of 25 these parts is therefore considered unnecessary.

It will be apparent that when the lower sash is raised as from the dotted line position to the full line position shown thereof in Fig. 1 of the drawings, there is provided an inclined louver space 21 for the passage of ventilating air as indicated by the arrows on the drawings. Likewise, when the upper sash is lowered as from the dotted line position to the full line position shown thereof in Fig. 1 of the drawings, there is provided an inclined louver space 28 for the passage of air as indicated by the arrows on the drawings. When the sashes are in closed position, the usual locking means (not shown) on rails l0 and I 9 will so cause a wedging action at the faces I B and i1, and

r faces 25 and 26 as to make the sashes press tightly against the guide rail 6 and thus prevent rattling and the like.

By providing the louver spaces 21 and 28 on a bias or incline, rain is shed and prevented from It is preferable not to raise the lower sash with the lower edge 29 of the rail portion I4 substantially above the level of the upper edge 30 of the rail portion 15, and likewise not to lower the upper sash with the upper edge 3| of the rail portion 23 substantially below the level of the lower edge 32 of the rail portion 24.

To increase the extent of the louver spaces and still have the advantage of rain shedding and the like, the invention comprehends the provision of auxiliary louver means.

As for example, in Figs. 2 and 3 is shown an auxiliary louver 33 having its ends 34 slidably mounted in inclined grooves or channels 35 provided in the sides of the window frame.

louver may be a sheet of glass, or metal, or wood, or fibre, or composition, etc., and it is slidable in the grooves with suflicient friction so as to remain in any given slid position. The grooves are in alinement with the louver surface I? so that the louver 33 may act substantially as an extension of the surface I! and yet may he slid down over the surface l1 (see dotted line position thereof in Fig. 2) whereby when the sash is in closed position the surface l6 will seat and seal with the upper face of the louver 33. When the louver 33 is in raised position as shown in full lines in Fig. 2, its upper edge 36 is substantially higher than the upper edge 30 of the rail part I 5, so that the lower sash may be raised 7 higher with the lower edge 29 of the rail portion the lower ends of channel M substantially on the level with the upper edge 36 of the louver 33. This provides for an increased louver space 2'! for permitting greater ventilation of air as shown by the arrows in Fig. 2 of the drawings.

While the above structure has been described in connection with the lower part of the window and the lower sash, the same means may be provided in the upper part of the window in connection with the upper sash except in inverted position.

Another type of auxiliary louver may be used as shown in Figs. 4, 5, and 6,

or without the same as shown in Fig. 4. In this case is provided an auxiliary louver 31 which may be of sheet metal or any other material as desired. The ends 38 of this louver are fast with the lower ends 39 of channel shaped bars 40 each of which is slidably mounted in a channel, which may be an extension of the rope channel, provided in each side rail of the sash. The inner face 4| of the bar 40 is provided with a slot 42 in which projects a pin 453 secured in the side rail H of the sash and in the back of the channel in the sash. Likewise in the upper part of the window is a like louver M the ends of which are fixed to shaped bars 45 each of which is slidably mounted in the usual rope channel or rope channel prolonged provided in each side rail of the upper sash. The inner face of this bar has a slot 46 in which projects a pin 4? secured to the end of rail portion 24 and in the back of the rope channel thereof.

Normally when the window sashes are closed the louver 3 is seated between the faces l6 and ll of the rail portions M and i5 and the louver 44 is seated between the faces 25 and 26 of the rail portions 23 and 24. When the lower sash is raised the louver 3'1 first remains seated on the face I until the pins 43 carried by the sash reach the upper ends of the slots 42 in the bars 40 after which the bars 40 and the louver 3'! are carried upward and attain the position shown in full lines in Fig. 4 of the drawings. The lower edge 48 of the louver 37 is about on the level with the upper edge 3 of the rail portion 15, and the lower edge 29 of the rail portion 14 is about on the level with the upper edge 49 of the louver 31. When lowering the sash, the louver 31 first descends with the sash until the louver seats on the face ill, and then the pins @3 descend in the slots 42 until the face it seats on the louver 31. By the above described means, an increased louver space is obtained.

When lowering the upper sash, the louver 44 first descends with the rail portion 23 until the upper end of the slot 46 contacts the pin 47 fixed in the sash part 24, then the sash continues to descend leaving the louver suspended as shown in full lines in Fig. 4 of the drawings. The upper edge 3| of the rail portion 23 is about on the same level as the lower edge SE of the louver 44 and the upper edge 5i of the louver 4 is about on the same level as the lower edge 32 of the rail portion 24, thus giving an increased louver space.

If it be desired to increase the louver space, the louver 33 may be used, the structure being the same as disclosed in connection with Figs. 2 and 3 of the drawings. In this case when the louver sash is raised the lower edge 48 of the louver 31 is about on the level with the upper edge 36 of the louver 33, thus giving further louver space.

In Figs. 7, 8 and 10 are shown further forms 55 having a handle 68,

"of auxiliary louvers for increasing the louver spaces. As shown in Fig. '7, a louver of sheet material, such as metal, comprises a base part 52 secured by screws 53 or other suitable securing elements to the rail portion 15, a resilient bend 54, louver or visor portion 55, and bead 56. The louver portion 55 extends substantially in alinement with the face l5 of the rail portion l4 so as to form a louver extension therefor. In this case when not using an auxiliary louver at the base, that is, with rail portion 15, the window sash may be raised with the bead 56 about level with the edge 30 of the rail portion 15. When the sash is closed, the louver part 55 engages the ledge 2 to over-lie it as shown in dotted lines in Fig. '1, the bend 54 acting as a resilient member for this purpose. When the sash is raised the louver portion 55 is restored in position to form an extension of the face l5 of rail portion 11.

However, to further increase the louver space, a louver 51 of sheet material, such as metal, may be provided, this louver having its ends 58 slidably mounted in grooves 59 provided in the sides 1 of the window frame and in alinement with the face l1 of the rail portion 15. The upper edge of the louver 51 preferably has a bead 5B. When the louver 51 is in its raised position as shown in full lines in Fig. '1, the sash may be so raised as to bring the bead 55 of the louver 55 about level with the bead 5 of the louver 51. When the louver 51 is lowered it seats on the face H of rail portion l5 and when the sash is closed the face lb of the rail portion 15 seats on the louver 51, as shown in dotted lines in Fig. '1. It will be noted that the bead 513 of the louver 51 is shorter (Fig. than the louver 51 itself, so that the ends 5| of the bead 56 will be flush with the inner surfaces of the stops 5 at the loci of the grooves 59.

In Fig. 8, is shown a louver 62 having a portion 63 secured as by screws or other suitable securing elements 64 to the rail portion 2 1 and a visor portion 65 in alinement with the face 26 of the rail portion 24 to form an extension of the face 25. The lower edge portion of the louver is provided with a head 55.

When the upper sash is lowered it may be lowered to the extent of having the edge portion 3| of the rail portion 23 about level with the bead 65, thus giving an increased louver space between the rail portions 23 and 25.

In the forms shown in Figs. 4, 5 and 6, if it be desired to set the auxiliary louver 31, a locking means may be provided comprising a head 61 and a screw shank 69 having an end portion adapted to lock or set the slide bar 19 to hold it and the louver 31 from sliding down when the window is raised. A similar means may be provided for the louver 14 for the upper sash when it is desired to prevent the louver sliding down when the upper sash is lowered.

InFigs. 11 and 12 is shown an auxiliary louver means similar to that shown in Figs. 4 and 5 but having an additional louver 10 secured to the upper ends of channel shaped bars 1| each slidable in a guide 12 and a passage 13 provided in the ledge 2, the guide 12 being secured in any suitable way via afiange 12. The inner wall of the bar 1| has a slot 14 in which extends a pin 15 secured to a fixed part in the guide channel as at the end of the rail portion l5. Between the lower ends 16 of the bars 1| and the lower ends 11 of the guide 12 are located springs 18 adapted to raise the bars 1| and the louver 11 connected to them into the position shown in Fig. 11. When the sash is closed, as shown in Fig. 12, the louver 10 seats on the face H of the rail portion 15, while the louver 31 seats on the louver 10, and the face 15 of the rail portion i l seats on the louver 31. When the sash is raised, the springs 18 lift the bars 1| and louver 10, as also louver 31, until the lower ends of the slots 14 contact the pins 15 whereby the louver 15 stops in spaced relation above the face I1. The continued raising of the sash causes the face it; to rise from louver 31, the latter remaining on louver 11! until the upper ends of the slots d2 hit pins 63 at which instant the louver 31 is picked up and raised from the louver 11 the face 15 being spaced from the louver 31. In this way three louver spaces are provided thus increasing the total louver space as clearly shown on the drawings. This is illustrative of providing as many louvers as desired in the sash space.
